‘I’ve struggled with psoriatic arthritis for 20 years. I have been on every medication, including methotrexate and biologics. Although some of these medicines worked for a while or had no effect on me, I realized that I pretty much gave up on myself. After spending a month in the hospital and nearly losing my kidney functions I decided to get a second opinion. I found Dr. Yu and he put me on a path to health that I forgot existed! He opened my eyes to a quality of life that for 20 years I had been seeking! I give him all the credit for my reinvigorated life and he, being the humble man he is tells me, ” you did all the work!” I have my life back and feel only joy, a joy that has replaced my pain! Thank you Dr. 1000 times thank you!” – Alex I.

Dr. Micah Yu is the absolute best. He has been very informative about my issues with Auto Immune Dieases. Prior to him becoming my doctor I had no idea what really was going on with my body. Because of him I’ve stopped smoking and am eating somewhat healthier. My struggles are not over by a long shot but I will say that I am in a better place than I was prior to him becoming my Rheumatologist. He’s compassionate and cares about his patients. He is leaving the facility where I have been treated however wherever he goes he’ll definitely be an asset to all he encounters. Love you Dr. Yu.” – Sheree O.
